> Regardless of your stance on immigration into the USA from South America

If you mean from places like Mexico, I will note that Mexico is in North America, not South America.

> anyone can see the hypocrisy in this right?

It's only hypocrisy if you assume every Mexican citizen is part of a hive mind, which they aren't, and also ignore the reasons for their views (e.g., that the opposition in Mexico City is largely opposition to white gentrification reinforcing preexisting elitism and white racism at the expensive of non-rich non-whites.)
